Atorvastatin is a 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitor, and this drug leads to decreased levels of low density lipoprotein (LDL) cholesterol. Lower LDL cholesterol has direct relationship in reducing mortality from coronary heart diseases. Lipitor (R) (atorvastatin calcium) was the first drug to reach the annual sales of 10 billion dollars in USA and currently is the top selling pharmaceutical product globally. Atorvastatin has a side chain containing two chiral centers as its pharmacophore and it can be synthesized either from chiral pool precursors, by using metal catalysts: or more preferably by the application of free or immobilized enzymes and whole cell biocatalysts for carrying out either asymmetric synthesis or racemic resolution. Biocatalytic synthesis methods for chiral atorvastatin intermediates employ a wide variety of biocatalysts such as alcohol dehydrogenase, 2-deoxy-D-ribose 5-phosphate aldolase, nitrilase, lipase, etc. and each of these biocatalytic processes is discussed in detail in this paper.
